Ekujongeni okusingqongileyo, ukhuseleko lwemizi-mveliso, kunye nohlalutyo lwelebhu,iimpompo zomoya ezincincizizinto ezibalulekileyo kwiinkqubo zokuthatha iisampulu zegesi. Xa kuhlalutywa iigesi ezirhabaxa, ukhetho lwezinto zokumpompa luchaphazela ngokuthe ngqo ukuchaneka kweziphumo zohlalutyo kunye nobomi benkonzo yezixhobo. Ukukhetha izinto ezingalunganga kunokubeka emngciphekweni umgangatho wedatha kwaye kukhokelela ekubeniimpompo yomoya ye-mini dcukusilela.

Eli nqaku linika isalathiso esicacileyo nesisebenzisekayo sokukhetha izinto ngendlela ethe ngqo.

Umgaqo-siseko: Gxila kuphela kwizixhobo ezidibana negesi

Kwiimpompo ezincinci, zizinto ezidibana ngqo negesi kuphela ezifuna ukuqwalaselwa ukuze zingangeni kumhlwa. Ezi zibizwa ngokuba zizinto "ezimanzi" kwaye ziquka:

1, Intloko/Isigqubuthelo sePump: Inika inkxaso yesakhiwo kwaye inendawo enkulu yokunxibelelana negesi.

2, i-Diaphragm: Inoxanduva lokudlulisa igesi, ifuna ukuguquguquka okuhle kunye nokumelana nokudinwa.

3, Iipleyiti/Iivalufa zeValve: Lawula indlela igesi ehamba ngayo, nto leyo efuna impendulo ekhawulezileyo kunye nokutywinwa kakuhle.

Izinto Eziphambili: Izinto Ezisetyenziswa "Ezimanzi" — Ukukhetha Phakathi Kweeplastiki Nee-Elastomers

Izinto ezisetyenziswa "kwisiphelo esimanzi" ziquka kakhulu izinto ezifana neeplastiki ezisebenza kakuhle (ezisetyenziselwa iintloko zepompo) kunye nee-elastomers ezisebenza kakuhle (ezisetyenziselwaiidiaphragms kunye neevalvu). Ngezantsi, siza kuqonda iimpawu zezi zinto, sigxile kwizinto "ezimanzi".

Izixhobo zeNtloko yePump: Ukulinganisela Amandla kunye nokumelana nokugqwala

Igama lezinto	Isifinyezo	Iimpawu eziphambili kunye nezicelo	Iintlobo zeGesi ezifanelekileyo
I-Polyphenylene Sulfide	I-PPS	Ukusebenza kakuhle xa iyonke. Amandla aphezulu oomatshini, ukumelana okuhle nobushushu, kunye nokunyamezelana okubanzi nee-asidi, ii-alkali, kunye nezinyibilikisi. Isetyenziswa kakhulu kuhlalutyo lwegesi yolwelo (SO₂, NOx).	Iiasidi ezibuthathaka, iialkali ezibuthathaka, izinyibilikisi eziqhelekileyo
I-Polyvinylidene Fluoride	I-PVDF	Ifanelekile kwi-oxidizers ezinamandla. Ichasana kakuhle neegesi ezinamandla ze-oxidizing ezifana ne-Cl₂, i-O₃, kunye nee-asidi ezinamandla.	Izixidizi ezinamandla, ii-asidi ezinamandla
I-Polytetrafluoroethylene	I-PTFE	Ayisebenzi kwiikhemikhali. Ayisebenzi kangako kwiikhemikhali. Ifanelekile kwiindawo ezifuna ubunyulu obuphezulu okanye ezinezinto ezintsonkothileyo nezirhabaxa zegesi.	Phantse zonke iikhemikhali

Icebiso Elisebenzayo: Ukuba igesi ine-chlorine okanye i-ozone ephezulu, kuyacetyiswa ukuba ukhethe intloko yepompo yePVDF okanye yePTFE, uphephe i-PPS.

Izinto zeDiaphragm/Valve: Ukulinganisela ukuqina kunye nozinzo

Iidiaphragms kunye neevalvu kufuneka zibe lula kwaye zikwazi ukumelana nokugqwala.

Igama lezinto	Isifinyezo	Iimpawu eziphambili kunye nezicelo	Ixabiso kunye nokuSebenza
I-Polyphenylene Sulfide	I-EPDM	Ixabiso liphantsi. Ukumelana kakuhle nee-asidi, ii-alkalis, kunye nomphunga wamanzi. Nangona kunjalo, ayixhathisi kakuhle kwiioyile kunye nezinye izinyibilikisi zendalo (ii-VOC).	Ixabiso liphantsi, lifanelekile kwiigesi ezirhabaxa eziqhelekileyo ezingenazo ii-VOC.
I-Polyvinylidene Fluoride	FKM	Isebenza ngeendlela ezininzi. Iyakwazi ukumelana nezinyibilikisi zendalo, iihydrocarbons (ii-VOC), kunye nee-asidi ezinamandla. Yi-elastomer esetyenziswa kakhulu kuhlalutyo lwemizi-mveliso.	Ixabiso eliphakathi, ukusebenza okuthembekileyo, kufanelekile kwiindawo ezininzi zoshishino.
I-Polytetrafluoroethylene	FFKM	Eyona ndlela ilungileyo yokumelana nokugqwala. Ukusebenza kweekhemikhali kufutshane ne-PTFE ngelixa kugcinwa ukuthamba kwerabha. Iyamelana phantse nazo zonke iikhemikhali.	Ixabiso liphezulu kakhulu, lisetyenziswa kuphela kwizicelo ezinzima kakhulu, ezibalulekileyo apho ukuphazamiseka kungeyondlela ifanelekileyo.

Icebiso Elisebenzayo: Ukuba igesi iqulethe naziphi na iihydrocarbons okanye izinyibilikisi zendalo (ii-VOC), musa ukukhetha i-EPDM. Endaweni yoko, khetha i-FKM okanye i-FFKM.

Inkqubo yeSigqibo samanyathelo amathathu: Ungakhetha njani ngokuchanekileyo?

Ukukhetha izinto eziphathekayo akubhekiselele ekukhetheni ukhetho olubiza kakhulu, kodwa malunga nokuhambelana nemeko yokwenyani.

Inyathelo 1: Chonga ukwakheka kwegesi kunye noxinzelelo

Le yeyona nto ibalulekileyo ekukhetheni izinto. Kufuneka wazi eyona nto ibangela ukubola kwigesi ekufuneka ilinganiswe kunye noxinzelelo lwayo oluphezulu.

• Umzekelo Wokuqala: Igesi yolwelo eqhelekileyo (uxinzelelo oluphantsi lwe-SO₂、NOx): Intloko yepompo ye-PPS + i-FKM diaphragm/iivalvu.
• Umzekelo Wesibini: Uhlalutyo lwe-chlorine kwizityalo ze-chlor-alkali (uxinzelelo oluphezulu lwe-Cl₂): Intloko yepompo ye-PVDF + i-FFKM diaphragm/iivalvu.

Inyathelo lesi-2: Cinga ngempembelelo yobushushu

Ubushushu bukhawulezisa ukugqwala. Izinto ezimelana nobushushu begumbi zinokungaphumeleli ngokukhawuleza xa kushushu kakhulu. Soloko ujonga iitshathi zokuhambelana kwezinto ezisekelwe kubushushu bokwenyani bokusebenza.

Inyathelo lesi-3: Ibhalansi yeendleko kunye nomngcipheko

• Iinkqubo eziphantsi zoMngcipheko/zesiqhelo: Khetha indibaniselwano ye-PPS/FKM ukuze ufumane umlinganiselo ongcono weendleko nokusebenza.
• Umngcipheko Omkhulu / Izicelo Ezibalulekileyo: Khetha indibaniselwano ye-PVDF/PTFE/FFKM. Nangona utyalo-mali lokuqala luphezulu, lubonelela ngobomi benkonzo ende kunye nokuthembeka okuphezulu kohlalutyo, nto leyo ebonisa ukuba ingabizi kakhulu ekuhambeni kwexesha.

Isikhumbuzo: Kuhlalutyo lwegesi erhabaxa, ukuhambelana kwezinto kubaluleke kakhulu. Ukusilela kwezinto akupheleli nje ekonakaleniimpompo yomoya encincikodwa mhlawumbi nakwiqela ledatha yohlalutyo olunempazamo.
